【摘要】 本文发展了一种非相干光图象消模糊的方法.采用了新的消模糊函数,它比起逆滤波器较易于制作.此函数与模糊图象在空域中进行卷积运算,能得到消模糊图象.在本系统中,可采用扩展单色光源和扩展白光源.由于运用非相干光源,使得在系统中引入了冗余度.因此,与通常的相干光系统相比,这种方法显著地提高了输出图象的信噪比.理论分析证明,此新消模糊函数是逆滤波函数的傅里叶变换.本文给出了实验结果.更多还原

【Abstract】 An incoherent image-deblurring method has been developed. We use a new deblurring function that is easier to implement than inverse filter. This function convolving with blurred image in spatial domain can get deblurring image. In this system, extended monochromatic source and extented white light source can be used. Because of the incoherent source, it introduces redundency in the system. So this method offers substantially improved noise performance compared to conventional coherent systems. Theoretical analysis shows that the new deblurring function is the Fourier transform of inverse filtering function. Experimental results are also given.更多还原
